The adsorption of methanol on Ni3Al(1 1 1) and NiAl(1 1 0) has been studied using high resolution photoemission spectroscopy (HR-PES) and density functional theory (DFT). Both methanol and methoxy are formed on these surfaces after the initial methanol exposure at low temperatures. Heating to 200 K leads to further formation of methoxy. On NiAl(1 1 0) two different methoxy species are observed whe
The construction and performance of the parallel plate avalanche counters (PPACs) using a spontaneous fission source Cf-252 is described in this paper. The parallel plate circular electrodes are made of aluminum foils having a thickness less than ten microns. After fabrication, the detectors and the source are mounted inside a reaction chamber, the source between the two detectors. A low pressure
I artikeln görs en översikt över jordbrukets och skogsbrukets närvaro i konsten i Sverige under 1900-talet. Den innehåller också analyser och diskussioner rörande hur, när och varför det agrara motivet är närvarande alternativt frånvarande i konsten under perioden.
Photosynthetic reaction centers convert sunlight into a transmembrane electrochemical potential difference, providing chemical energy to almost all life on earth. Light energy is efficiently transferred through chromophore cofactors to the sites, where charge separation occurs. We applied two-dimensional electronic spectroscopy to assess the role of coherences in the photoresponse of the bacterial
Since any firearm injury is potentially lethal, it is of great interest to prevent firearm incidents. This study investigated such incidents during hunting and Swedish hunters' safety behaviour. A 48-item questionnaire was posted to a random sample of 1000 members of the Swedish Association for Hunting and Wildlife Management. The questions considered demographics, hunting experience/hunting habit
Physicians’ attitudes towards disclosure to patients of cancer diagnoses have changed from non-disclosure to full disclosure. Also disclosure of prognosis are likewise said to have changed, though not to the same degree. The overriding aim of this dissertation is to analyse information disclosed to patients with severe cancer prognoses, from a Swedish perspective, through two sets of interviews wi

Popular Abstract in Swedish Akut mediaotit - öroninflammation - är den vanligaste bakteriella infektionen hos barn. Den vanligaste öroninflammationsbakterien är pneumokocken. Öroninflammation är en infektion som varierar stort i svårighetsgrad; medan många öroninflammationer läker utan behandling kan andra ge upphov till livshotande komplikationer. Eftersom självläkningsfrekvensen är ganska hög oAcute otitis media (AOM) is the most common bacterial infection in children. The clinical course varies from spontaneous recovery to life-threatening complications, and this variability mainly depends on the causative pathogen. Bacteria usually invade the middle ear from the nasopharynx, where they are carried frequently, both during sickness and health. The most common bacterium to cause AOM, and
High uncertainties are common in detailed quantification of the N budget of agricultural cropping systems. The process-based CoupModel, integrated with the parameter calibration method known as Generalized likelihood uncertainty estimation (GLUE), was used here to define parameter values and estimate an N budget based on experimental data from an organic farming experiment in south-west Sweden. Da
Incubation is a period of high energetic costs and accordingly body mass losses are often detected. Why birds lose body mass during incubation is not well understood; suggestions are that it is either a consequence of energetic constraints or adaptations to an optimal mass trajectory. We studied body mass changes through the incubation period in the Common Redshank Tringa totanus, a biparental inc
We study transfer of coherent nuclear oscillations between an excitation energy donor and an acceptor in a simple dimeric electronic system coupled to an unstructured thermodynamic bath and some pronounced vibrational intramolecular mode. Our focus is on the nonlinear optical response of such a system, i.e., we study both excited state energy transfer and the compensation of the so-called ground-s
We derive a zero-range pseudopotential that includes all possible terms up to sixth order in derivatives. Within the Hartree-Fock approximation, it gives the average energy that corresponds to a quasilocal nuclear energy density functional (EDF) built of derivatives of the one-body density matrix up to sixth order. The direct reference of the EDF to the pseudopotential acts as a constraint that di
Several diesel exhaust (DE) characteristics, comprising both particle and gas phase, recognized as important when linking with health effects, are not reported in human chamber exposure studies. In order to understand effects of DE on humans there is a need for better characterization of DE when performing exposure studies. The aim of this study was to determine and quantify detailed DE characteri
Allergic rhinitis is a major atopic disease. Even if much is known about the pathophysiology of this condition, and despite the fact that good treatments are available, there is a need for new treatment options, particularly for such aiming at new targets and reduced side effects. Recruitment and activation of eosinophils is a key feature of allergic rhinitis. Eosinophils have different activatio
The automotive industry is experiencing tightening emission legislations together with high demands on performance and driveability. As a counteraction, controller software tends to become more and more complex. Intricate controller software has several downsides, the large number of controller parameters yields an exhaustive calibration task, often performed through costly experiments. In additio
An all digital phase-locked loop (ADPLL) has been implemented in a 90-nm CMOS process. It uses a phase-frequency detector (PFD) connected to two time-to-digital converters (TDC). To save power the TDCs use delay line cells with uneven delay time. During frequency acquisition an automatic tuning bank controller selects active bank of the digitally controlled oscillator (DCO), which features three s
Although the familial clustering of multiple myeloma (MM) supports the role of inherited susceptibility, only recently has direct evidence for genetic predisposition been demonstrated. A meta-analysis of two genome-wide association (GWA) studies has identified single-nucleotide polymorphisms (SNPs) localising to a number of genomic regions that are robustly associated with MM risk. In this review,
We present a study on the electronic properties of grain boundaries (GBs) in polycrystalline Cu(In,Ga)Se-2 (CIGSe) thin films by means of Kelvin probe force microscopy. As grown as well as KCN-treated films were investigated comparatively. No influence of the chemical treatment on the electronic properties of GBs was found. GBs generally exhibited large variations in their electronic properties. B
